Duct Fiber Optic Cable Manufacturer

For Underground & Conduit Installation

Choose The Right Duct Fiber Optic Cable

Choosing the right duct fiber optic cable is essential for ensuring reliable performance, long service life, and cost efficiency in your network. Different installation environments require different cable structures, protection levels, and scalability options.

GYTA – Aluminum Armored Cable

GYTA is designed with aluminum tape armoring, offering a balanced combination of flexibility and protection. It is widely used in underground conduit systems where moderate mechanical strength is required. The aluminum layer helps prevent moisture ingress and improves overall durability.

GYTS – Steel Tape Armored Cable

GYTS uses steel tape armoring to provide stronger resistance against crushing forces and rodent damage. It is suitable for long-distance duct installations or environments with higher mechanical risks. This type is often chosen for backbone telecom networks.

GYTA53 (Double Armored Heavy-Duty Cable)

GYTA53 features a double armored structure with aluminum tape and steel tape, providing enhanced mechanical protection and moisture resistance. It is suitable for both duct and direct burial installations, especially in environments where higher crush resistance and durability are required. The dual-layer design ensures long-term stability in harsh underground conditions.

GYFTY Non-Metallic Fiber Optic Cable

GYFTY is a fully non-metallic fiber optic cable designed with FRP strength members, offering excellent lightning resistance and anti-electromagnetic interference performance. It is ideal for duct installations near power lines or in high-voltage areas where electrical insulation is essential. The lightweight and corrosion-free design ensures reliable performance in complex environments.

GYFTY53 Non-Metallic Armored Fiber Optic Cable

GYFTY53 is a heavy-duty non-metallic armored cable with a double sheath structure, designed for harsh outdoor environments. It provides superior mechanical strength, moisture protection, and resistance to external damage, making it suitable for direct burial and duct installations. Its fully dielectric design ensures safe operation in high-voltage and interference-prone areas.

Frequently Asked Questions 1

Which duct fiber optic cable should I choose?

Short Answer:

It depends on your project requirements.

Expanded Answer:
● Use armored cables (GYTA / GYTS) for high-pressure or rodent-risk environments
● Use non-armored cables (GYTY) for cost-sensitive or protected ducts
● Use microduct cables (GYFQY) for FTTH and scalable networks
You should also consider conduit condition, installation method, and future expansion needs.

What is the difference between duct and direct buried cable?

Short Answer:
Duct cables are installed inside conduits, while direct buried cables are placed directly underground.

Expanded Answer:
Duct systems allow easier maintenance, replacement, and upgrades.
Direct buried cables require stronger mechanical protection but have lower initial infrastructure costs.
